I'm searching for a C++ library to solve linear equation systems. The problem is we need to use a special (rational) data type. Is there any templated library for this purpose?

@djf: it's not a duplicate because a _templated_ library is required. The answers below are already helpful, thanks a lot! – Geom Jul 02 '13 at 14:03

Take a look into Eigen:
"Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms"

I believe this library may be what you're looking for. It is templated http://www.boost.org/doc/libs/1_54_0/libs/numeric/ublas/doc/index.htm
